Biography
Leopold of Bavaria joined the army at the age of 15 in 1861 and in 1866 fought as the commander of Bavarian artillery batteries in the Austro-Prussian War in the battles of Kissingen and Rossbrunn. He later served in the Franco-Prussian War after Bavaria became a part of the German Empire federation. In 1905 he became a Field Marshal and retired in 1913, but was called out of retirement in 1915 during World War I to command the German and Austro-Hungarian forces on the Eastern Front fighting Russia. He reversed the Brusilov Offensive in 1916-1917 and ended his career in success in 1918 after the Treaty of Brest-Litovsk ended the Russo-German-Austrian War.
